Because when I'm on my big honkin', sets-off-car-alarms loud, chrome-covered motorcycle... it is only white people in European SUVs that don't notice me and nearly kill me on a regular basis. Then they have the balls to keep talking on their cell phones and give me dirty looks when they merge 6" in front of my fender at 70 mph.
Hating white people doesn't have a social no-no stigma yet, either.
Lame link for you:
White People Suck
